Detox symptoms, or genuinely sick?

Hi !

Recently I've started the Primal way of eating and went cold turkey.
No grains, no refined sugars, no processed soups,drinks,meats (etc)

After a few days I developed acne, then I became fatigued, muscle pains and my mind fogged up. My appetite reduced and my cravings for "carby foods" seemed to vanish. As the days progressed, I started to get a phlegm cough, then irritable and having anxiety. Then a few days later out of the blue, a full fledged cold takes hold of me,( sneasing almost nonstop, sweating etc) but only really lasted about a day and a half. For me colds don't usually go away that quickly. The coughing up phlegm is still persisting and now memory loss . It's hard to fall asleep due to the coughing and irritability. Also, just recently, ear pain!
I've stayed home from work for the last 2 days because I feel sensitive to stress.

So guys, what do you think? :/
Am I genuinely sick, or lacking nutrients, or detoxing?

I wouldn't want to have the doctor shove down antibiotics in me if my body was simply clearing out excess junk.

Treat yourself to a smokin' hot shower. It should at least help alleviate some of the discomfort you're experiencing. I was hanging out in the steam room at my gym the other day and all the gunk in my nose bailed and my muscles got SOOOO relaxed. It was awesome.
